Definitions
- the present invention relates to a motor vehicle gearbox comprising a housing with an input shaft, which carries a number of gears corresponding to the number of gear speeds forward, and two countershafts which lie in a plane offset from the input shaft and have gears in engagement with the gears on the input shaft, at least one gear of each pair of interengaging gears on said shafts being disengageable on its shaft, one of said disengageable gears being mounted on one of the countershafts and being disposed to transmit torque in first gear to a final drive, while another is mounted on the input shaft and is disposed to transmit torque in the highest gear to the final drive.
- a gearbox of the above described type is known e.g. by SE-A-8601247-3 (& US-A- 4 776 227). It has five gear speeds forward and one in reverse. The torque is transmitted in reverse from the input shaft via one countershaft to the other countershaft by virtue of the fact that a gear, joined to the hub of the disengageable gear for a first gear speed, on one countershaft engages a disengageable reverse gear on the other countershaft. This eliminates the need for a separate shaft for the reverse countergear. Instead, the first mentioned countershaft can also be used as a reverse gear shaft. This provides an especially compact, simple and inexepensive design which with its small axial dimensions is particularly suited for use together with transverse engines.
- the purpose of the present invention is, starting from the above described known gearbox, to achieve a gearbox design, the five speed version of which can constitute the basic design for a six speed version.
- the five speed gearbox will have their counterparts as regards number and relevant placements in the six speed gearbox.
- disengageable gear for transmitting torque in first gear engages an additional gear, which is carried disengageably by a fourth shaft and is arranged to transmit reversing torque to the final drive.
- the design according to the invention involves, compared with the known five speed gearbox, that the gear joined to the hub of the disengageable gear for the first gear speed is eliminated and that the disengageable reverse gear is moved from one countershaft to an extra shaft and is driven directly by the disengageable gear for the first gear speed. This makes room for an extra pair of gears for a sixth gear speed without requiring any increase in the axial dimensions of the gearbox.
- the disengageable gear for the highest gear speed on the input shaft when expanding a five speed gearbox to a six speed gearbox, the disengageable gears of both fifth and sixth will be journalled on the same shaft, which provides a suitable shift pattern for the movement of the gear lever at the same time as production costs are optimised by parallel production of both types.
- a gearbox housing generally designated 1 in Fig. 1, and which also forms a housing for a clutch, an input shaft 2, a first countershaft 3, a second countershaft 4 and a reverse shaft 5 are rotatably mounted.
- the input shaft 2 carries the disc 6 of the clutch and five gears 7, 8, 9, 10 and 11, of which the gears 7, 8, 9 and 10 are non-rotatably fixed to the shaft 2, while the gear 11 is a disengageable gear, i.e. it is rotatably mounted on its shaft but can be locked or released in a conventional manner by means of an engaging sleeve 12 with associated synchronizing means.
- a pair of gears 15 and 16 are rotatably mounted and are lockable to the shaft by means of an engaging sleeve 17 comprising synchronizing means.
- a pair of gears 18 and 19 are rotatably mounted and can be locked to the shaft by means of an engaging sleeve 20 with synchronizing means.
- the countershaft 4 also carries a gear 21 which is non-rotabably joined to the shaft.
- a gear 22 is rotatably mounted and can be locked to the shaft by means of an engaging sleeve 23 with synchronizing means.
- a pair of gears 24 and 25 of equal size are each non-rotatably fixed to its respective countershaft 3, 4 and each engages a crown wheel 26 in a differential generally designated 27.
- a gear 28, which is somewhat smaller than the gears 24, 25, is non-rotatably fixed to the reverse shaft 5 and engages the crown wheel 26.
- the disengageable gear 18 When shifting from first to reverse, the disengageable gear 18 is disengaged and the reverse disengageable gear 22 is engaged instead by means of the clutch 23, and the disengageable gear 18 for first, which engages the reverse disengeable gear 22, serves as a countergear to impart a direction of rotation to the reverse shaft 5 which is opposite to the rotational direction of the countershafts 3, 4.
- gearbox can be made even shorter than the very shortest five speed gearboxes known up till now.
- a six speed version which is shown in Fig. 2 and will be described below, can be achieved by simply building out the five speed version and the length of the six speed version need not exceed the length of the shortest hitherto known five speed gearboxes.
- a gear 30 is freely rotatably mounted on the extension of the input shaft 2 and can be locked to the input shaft by means of the same engaging sleeve 12 that locks the gear 11.
- torque is transmitted to the crown wheel 6 of the differential 7 via the engaged gear 30, a gear 31 fixed to the extension of the countershaft 4 and the gear 25.
